Description

Technical Field

[0001] This invention relates to the field of vehicle air conditioning system technology, and in particular to an air conditioning assembly structure and vehicle that completely eliminates external condensate. Background Technology

[0002] With the development of science and technology and the improvement of people's living standards, cars are becoming more and more popular. Car air conditioning is a very important part of the car, mainly used to adjust and control the temperature, humidity, air cleanliness and air flow in the car cabin to the optimal state. This not only makes the user more comfortable during the driving process and reduces travel fatigue, but also removes fog from the car windows when the outside temperature is much lower than the inside temperature, making driving safer.

[0003] With the development of the automotive industry, modern cars, not only sedans, minibuses, and buses, are now widely equipped with air conditioning systems, but even trucks in many models are now equipped with them. Therefore, automotive air conditioning and its accessories have become essential components in automobile manufacturing.

[0004] Air conditioning assemblies typically have an evaporator built-in. The evaporator operates at a relatively low temperature (1-5°C). The contact between the evaporator and the housing results in a lower outer surface temperature for the housing and a higher outside air temperature (above 25°C). This temperature difference causes the hot outdoor air to cool rapidly and condense, accumulating on the housing's outer surface. This condensate then flows into the passenger compartment. Prolonged use of the air conditioning in hot and humid areas can lead to significant condensation inside the passenger compartment. Improper water handling can result in water dripping onto the wiring harness, creating a safety hazard.

[0005] In related technologies, to reduce condensation on the air conditioning assembly, a molded sponge is typically attached to the outside of the casing to prevent direct contact between outside air and the casing. However, after the air conditioning has been running for a long time, the sponge temperature becomes as low as the casing temperature, resulting in a large amount of condensation that drips into the passenger compartment.

[0006] Therefore, it is necessary to design a new air conditioning assembly structure and vehicle that completely eliminates external condensation in order to overcome the above problems. Summary of the Invention

[0007] This invention provides an air conditioning assembly structure and vehicle that completely eliminates external condensation, thereby solving the problem in related technologies where a molded sponge is attached to the outside of the outer casing to prevent direct contact between external air and the casing. However, after the air conditioning has been running for a long time, the temperature of the sponge is as low as that of the casing, resulting in a large amount of condensation that drips into the passenger compartment.

[0008] In a first aspect, an air conditioning assembly structure that completely eliminates external condensate is provided, comprising: an outer casing, a blower mounted on one side of the outer casing, the blower having an air outlet; an inner casing located inside the outer casing and spaced apart from the outer casing to form an air cavity between the inner casing and the outer casing, an evaporator disposed within the inner casing, and a drain outlet provided at the bottom of the inner casing; the air cavity communicating with the air outlet, and the bottom of the air cavity communicating with the drain outlet.

[0009] In some embodiments, an air inlet communicating with the air blower is provided on one side of the air cavity, and both the air inlet and the air blower are located in the positive pressure zone of the blower.

[0010] In some embodiments, the air inlet is funnel-shaped, and its inner diameter gradually increases from the connection point with the air cavity towards the air outlet. The closed-end design of the air inlet helps to increase the air velocity at the top of the air cavity, enabling rapid water blowing and preventing the formation of a water column.

[0011] In some embodiments, the air inlet extends downwards and towards the air outlet from its connection with the air cavity. This facilitates the air entering the air cavity to first contact the inner wall surface of the outer casing, rapidly increasing the temperature of the outer casing and making its temperature comparable to the outside air temperature; simultaneously, it helps to fill the air cavity with outside air.

[0012] In some embodiments, the inner housing includes a first vertical plate and a second vertical plate arranged in parallel, and a top plate connecting the first vertical plate and the second vertical plate. The top plate is arranged at an angle to the first vertical plate and the second vertical plate. The air cavity includes a first cavity located between the first vertical plate and the outer housing, a second cavity located between the second vertical plate and the outer housing, and a third cavity located between the top plate and the outer housing. The air inlet is located at the connection between the second cavity and the third cavity, and the air inlet communicates with the second cavity and the third cavity.

[0013] In some embodiments, the inner housing further includes a first base plate connected to the first vertical plate and a second base plate connected to the second vertical plate, wherein the angle between the first base plate and the first vertical plate is an obtuse angle, and the angle between the second base plate and the second vertical plate is also an obtuse angle; the air cavity further includes a fourth cavity located between the first base plate and the outer housing, and a fifth cavity located between the second base plate and the outer housing, wherein the fourth cavity communicates with the first cavity, the fifth cavity communicates with the second cavity, and both the fourth cavity and the fifth cavity extend downward at an angle.

[0014] In some embodiments, the air conditioning assembly structure further includes a connecting cavity, the connecting cavity connecting the fourth cavity and the drain outlet, the angle between the axis of the connecting cavity and the axis of the drain outlet is an acute angle, and the connecting cavity and the fourth cavity are arranged at an angle; the bottom of the fourth cavity is connected to the bottom of the fifth cavity.

[0015] In some embodiments, the inner diameter of the fourth cavity gradually increases from the connection point with the first cavity toward the drain outlet, and the inner diameter of the fifth cavity gradually increases from the connection point with the second cavity toward the drain outlet; furthermore, the inner diameter of the fourth cavity at the end near the first cavity is smaller than the inner diameter of the first cavity, and the inner diameter of the fifth cavity at the end near the second cavity is smaller than the inner diameter of the second cavity.

[0016] In some embodiments, an air inlet communicating with the air blower is provided on one side of the air cavity, and a plurality of water grooves are arranged on the surface of the inner shell, the water grooves extending from the air inlet toward the direction close to the drain outlet.

[0017] Secondly, a vehicle is provided that includes the aforementioned air conditioning assembly structure that completely eliminates external condensate.

[0018] The beneficial effects of the technical solution provided by this invention include:

[0019] This invention provides an air conditioning assembly structure and vehicle that completely eliminates external condensation. By adding an outer shell to the evaporator housing, an air cavity is formed between the outer shell and the inner shell. External air can be blown into the air cavity by the blower, thereby draining the water in the air cavity through the drain port at the bottom of the inner shell. The air entering the outer shell is at almost the same temperature as the air outside the outer shell, so no condensation will form on the surface of the outer shell, and therefore will not drip into the passenger compartment.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides an air conditioning assembly structure that completely eliminates external condensation. It solves the problem in related technologies where a molded sponge is attached to the outside of the outer casing to prevent direct contact between external air and the casing. However, after the air conditioner has been running for a long time, the temperature of the sponge is as low as that of the casing, resulting in a large amount of condensation that drips into the passenger compartment.

[0032] See Figure 1As shown in the figure, an air conditioning assembly structure that completely eliminates external condensate water according to an embodiment of the present invention may include: an outer shell 1, on one side of which a blower 2 is mounted, the blower 2 having an air outlet, wherein the blower 2 can draw in outside air and blow outside air out through the air outlet; and an inner shell 3, located inside the outer shell 1, wherein the inner shell 3 and the outer shell 1 may have the same or different structural shapes, and the inner shell 3 and the outer shell 1 are spaced apart, forming an air cavity 4 between the inner shell 3 and the outer shell 1. 4. Water and gas can be supplied for circulation. The evaporator 5 is provided inside the inner shell 3, and a drain port 6 is provided at the bottom of the inner shell 3. The inner shell 3 is the shell of the evaporator 5. Water and other substances on the surface of the evaporator 5 can flow inside the inner shell 3 and be discharged through the drain port 6 at the bottom. Furthermore, the air cavity 4 is connected to the air outlet, and the bottom of the air cavity 4 is connected to the drain port 6, so that the external air blown out by the blower 2 can enter the air cavity 4 and gradually flow to the drain port 6, and be blown out through the drain port 6.

[0033] In this embodiment, an outer shell 1 is added outside the evaporator 5, forming an air cavity 4 between the outer shell 1 and the inner shell 3. External air can be introduced into the air cavity 4 via the blower 2, blowing away water within the air cavity 4 along its extension direction. The water is then discharged through the drain port 6 at the bottom of the inner shell 3. Since the air entering the outer shell 1 is at almost the same temperature as the air outside, there is no temperature difference, preventing condensation from forming on the outer surface of the outer shell 1 and thus preventing dripping into the passenger compartment, avoiding safety hazards. The inner shell 3 will form a certain amount of condensation due to the temperature difference between the air cavity 4 and the evaporator 5. Since the condensation in the air cavity 4 is connected to the drain port 6 of the air conditioner itself, the condensation can be discharged outside the passenger compartment through the internal drain port 6. Therefore, regardless of the outside air temperature and humidity, no condensation will form on the coldest part of the air conditioner, the outer shell 1.

[0034] In some embodiments, see Figure 1As shown, one side of the air cavity 4 may be provided with an air inlet 7 that communicates with the air blower. That is, the air inlet 7 can communicate with the air cavity 4, and the air inlet 7 extends from the point of communication with the air cavity 4 towards the air blower. Both the air inlet 7 and the air blower are located in the positive pressure zone of the blower 2. That is, the air blower is also located in the positive pressure zone, and the air inlet 7 is also located in the positive pressure zone. By placing both the air blower and the air inlet 7 in the positive pressure zone, a pressure difference is formed between the air inlet 7 and the drain outlet 6, which is conducive to the condensate inside the air cavity 4 flowing with the air pressure and being discharged quickly; and avoids the backflow of condensate inside the air cavity 4, which would cause drainage difficulties.

[0035] In some alternative embodiments, see Figure 1 and Figure 2 As shown, the air inlet 7 is preferably funnel-shaped, and its inner diameter gradually increases from the connection point with the air cavity 4 towards the air outlet. In this embodiment, the air inlet 7 adopts a closed design, which is beneficial for increasing the air velocity at the outlet of the upper air cavity 4, achieving rapid water blowing, and avoiding the formation of a water column. Of course, in other embodiments, the air inlet 7 can also be designed as a straight line or other curved shapes.

[0036] In some embodiments, see Figure 2 As shown, the air inlet 7 extends downwards and towards the air outlet from its connection with the air cavity 4. That is, viewed from the air outlet, the air inlet 7 extends obliquely upwards. This allows air to be blown obliquely upwards along the oblique direction of the air inlet 7 as it enters the air cavity 4. This facilitates the air's contact with the inner wall of the outer casing 1 upon entering the air cavity 4, rapidly increasing the temperature of the outer casing 1 until it matches the outside air temperature. Simultaneously, it helps to fill the air cavity 4 with outside air. Of course, in other embodiments, the air inlet 7 can be designed in any direction according to actual needs.

[0037] In some alternative embodiments, see Figure 1As shown, the inner shell 3 may include a first vertical plate 31 and a second vertical plate 32 arranged in parallel, and a top plate 33 connecting the first vertical plate 31 and the second vertical plate 32. The top plate 33 is arranged at an angle to the first vertical plate 31, and the top plate 33 is arranged at an angle to the second vertical plate 32. The angle between the top plate 33 and the first vertical plate 31 can be a right angle, an acute angle, or an obtuse angle, and the angle between the top plate 33 and the second vertical plate 32 can also be a right angle, an acute angle, or an obtuse angle. When the angle between the top plate 33 and the first vertical plate 31 is an acute angle, the angle between the top plate 33 and the second vertical plate 32 is an obtuse angle. In this embodiment, since the evaporator 5 has a cuboid structure, it is preferable to... The inner shell 3 is also designed as a cuboid structure, that is, the top plate 33 is perpendicular to the first vertical plate 31 and the top plate 33 is perpendicular to the second vertical plate 32; the air cavity 4 may include a first cavity 41 located between the first vertical plate 31 and the outer shell 1, a second cavity 42 located between the second vertical plate 32 and the outer shell 1, and a third cavity 43 located between the top plate 33 and the outer shell 1. The third cavity 43 is located between the first cavity 41 and the second cavity 42, and the first cavity 41 communicates with the third cavity 43, and the second cavity 42 communicates with the third cavity 43, thereby realizing mutual communication between the first cavity 41, the second cavity 42, and the third cavity 43.

[0038] The air inlet 7 is located at the connection between the second cavity 42 and the third cavity 43. The air inlet 7 connects to the second cavity 42 and the third cavity 43. That is, there is a corner at the connection between the first cavity 41 and the third cavity 43, and there is also a corner at the connection between the second cavity 42 and the third cavity 43. The air inlet 7 is connected to the corner between the second cavity 42 and the third cavity 43, so that when the external air is blown in from the air inlet 7, it can be split into two paths at the corner between the second cavity 42 and the third cavity 43. One path blows towards the third cavity 43 and then into the first cavity 41, and the other path blows into the second cavity 42, thereby completely blowing out the condensate on the surface and sides of the inner shell 3 at one time. Furthermore, since water easily accumulates on the surface of the top plate 33, placing the air inlet 7 at the corner between the second cavity 42 and the third cavity 43 also facilitates air to be blown out from one side of the top plate 33 along the top plate 33, allowing condensate to flow out along the top plate 33.

[0039] Further, see Figure 1As shown, the inner shell 3 may further include a first base plate 34 connecting the first vertical plate 31 and a second base plate 35 connecting the second vertical plate 32. The angle between the first base plate 34 and the first vertical plate 31 is an obtuse angle, and the angle between the second base plate 35 and the second vertical plate 32 is also an obtuse angle. This allows the first base plate 34 to extend downwards at an angle relative to the first vertical plate 31, and the second base plate 35 to extend downwards at an angle relative to the second vertical plate 32. The first base plate 34 and the second base plate 35 extend downwards at an angle towards each other, which facilitates the flow of water in the inner shell 3 along the first base plate 34 and the second base plate 35 to the drain outlet 6 under the action of gravity. The air cavity 4 may further include a fourth cavity 44 located between the first base plate 34 and the outer shell 1, and a fifth cavity 45 located between the second base plate 35 and the outer shell 1. The fourth cavity 44 communicates with the first cavity 41, and the fifth cavity 45 communicates with the second cavity 42. Both the fourth cavity 44 and the fifth cavity 45 extend downwards at an angle. The downwardly extending fourth cavity 44 and fifth cavity 45 enable the condensate in the fourth cavity 44 and fifth cavity 45 to tend to flow towards the drain outlet 6 under the action of gravity. That is, in addition to the air blowing the condensate in the air cavity 4, gravity can also drive the condensate to flow, which can reduce the resistance of air flowing in the air cavity 4.

[0040] In some alternative embodiments, see Figure 1 As shown, the air conditioning assembly structure may further include a connecting cavity 8, which connects the fourth cavity 44 and the drain outlet 6. The angle between the axis of the connecting cavity 8 and the axis of the drain outlet 6 is an acute angle, and the connecting cavity 8 and the fourth cavity 44 are set at an angle. That is, the axis of the connecting cavity 8 is not collinear with the axis of the fourth cavity 44. Condensate flowing into the fourth cavity 44 can enter the connecting cavity 8 and then flow through the connecting cavity 8 to the drain outlet 6 for discharge. By setting the connecting cavity 8, which is not collinear with the fourth cavity 44, it is possible to prevent condensate from flowing back to the upper part of the fourth cavity 44. The bottom of the fourth cavity 44 is connected to the bottom of the fifth cavity 45, so that condensate in the fifth cavity 45 can enter the fourth cavity 44 and then enter the connecting cavity 8 from the fourth cavity 44 for discharge.

[0041] Furthermore, in some optional embodiments, see [link to documentation]. Figure 1 As shown, the inner diameter of the fourth cavity 44 can gradually increase from the connection point with the first cavity 41 towards the drain outlet 6, and the inner diameter of the fifth cavity 45 can gradually increase from the connection point with the second cavity 42 towards the drain outlet 6.

[0042] Furthermore, the inner diameter of the fourth cavity 44 near the first cavity 41 is smaller than the inner diameter of the first cavity 41, and the inner diameter of the fifth cavity 45 near the second cavity 42 is smaller than the inner diameter of the second cavity 42. Making the fourth cavity 44 and the fifth cavity 45 into a constricted shape facilitates increasing the drainage pressure at the drain outlet 6.

[0043] In some embodiments, see Figure 3 As shown, one side of the air cavity 4 may be provided with an air inlet 7 communicating with the air outlet. The surface of the inner shell 3 is arranged with multiple water grooves 36, which extend from the air inlet 7 towards the drain outlet 6. The water grooves 36 are arranged perpendicular to the air flow direction within the air cavity 4, while their extension direction is along the air flow direction within the air cavity 4. Water grooves 36 can be provided on the first vertical plate 31, the second vertical plate 32, and the top plate 33 of the inner shell 3. In this embodiment, the water grooves 36 can hold water, facilitating the accumulation of condensate within them, which is then quickly drained by airflow.

[0044] Preferably, in this embodiment, the structural shape of the outer shell 1 can be approximately the same as that of the inner shell 3. That is, in this embodiment, the inner shell 3 has a cuboid structure, and the outer shell 1 can also have a cuboid structure. Specifically, the outer shell 1 may include a first plate 11, a second plate 12, and a third plate 13. The first plate 11 and the first vertical plate 31 form the first cavity 41, the second plate 12 and the second vertical plate 32 form the second cavity 42, and the third plate 13 and the top plate 33 form the third cavity 43.

[0045] This invention also provides a vehicle that may include a driver's cab and an air conditioning assembly structure provided in any of the above embodiments that completely eliminates external condensate, installed in the driver's cab.
